工作在10.6微米波长的测距机在低能见度条件下具有良好的性能,其光学元件与热视系统兼容并且对眼睛安全;这些优点对军事应用特别重要.为了证实以这一波长测距的可行性,我们研制了脉冲CO_2激光测距机样机.这部样机具有组件式结构,在发射机装置中使用一台马可尼航空电子学公司制造的封离式横向激励大气压CO_2激光管.接收装置使用锗光学系统以及冷却到77°K的碲锡铅探测器.该测距机已对各种目标进行了试验,证实了可达9公里、精度为±5米的测距性能.
Range finders operating at a wavelength of 10.6 microns have good performance in low visibility conditions, their optics are compatible with thermal systems and eye-safe; these advantages are particularly important for military applications. In order to confirm the feasibility of this wavelength range finding We developed a prototype of a pulsed CO_2 laser range finder with a modular construction using an enclosed, horizontally excitable atmospheric CO 2 laser tube manufactured by Marconi Avionics in a transmitter unit. Using a germanium optical system and a tellurium-tin-lead detector cooled to 77 ° K. The range finder has been tested on various targets and has proven to be capable of measuring distances of up to 9 km with an accuracy of ± 5 meters.
